PreCheck is the TSA program that lets you bypass the lengthy “standard” security lines at US airports. If you have PreCheck you can use the short line, leave shoes on and leave liquids and computers in your carry-on luggage.

Now Frontier and Spirit have indicated that they will join PreCheck…the last US-based carriers to do so.

The six are American Airlines, Frontier, JetBlue, Silver Airways, Southwest, and Sun Country. They will fly to Cuban cities other than Havana, but in the future some may be approved to that popular destination.

The origination cities in the US are Miami, Fort Lauderdale, Chicago, Minneapolis/St. Paul, and Philadelphia.

Americans continue to face significant obstacles to Cuban travel, due to the continuing “12 reasons” rule. Abolition of these restrictions may depend upon Congressional action.

As the Zika virus spreads from South America into Caribbean island nations (including the U.S. Virgin Islands), airlines have begun letting passengers cancel flights without penalty.

If you or your partner are or could be pregnant, call the airline to learn if you can cancel for a full refund. The airlines are changing their policies on this daily, so Hang Up / Call Again (“HUCA”) tomorrow if you do not get a good answer today.

You can see a map from the Center for Disease Control showing areas of the United States where Aedes aegypti and Aedes albopictus mosquitoes capable of spreading Zika virus are found.
